+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,

+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>

+To convert in-game player name colors to html display.

+    https://gitlab.com/xonotic/xonstat/blob/master/xonstat/util.py
+
+Overview:
+
+    This component is slightly based on util.py of XonStats, but the only 
+    functionality needed is coloring the player's names. Since C programming 
+    language does not have standard libraries for color model conversions and 
+    regex, some functionality had to be self written. The function of interest 
+    is:
+        def html_colors(qstr='', limit=None):
+
+    This component uses purely C standard library.
+
+    Advanced string manipulations such as replace and concatenation are 
+    avoided. Instead, strings are printed in parts across functions.
+
+    There is only one instance of dynamic memory allocation. 
+        void print_plname(const char *)
+    It both allocates, near the start, and frees memory at the end.
+
+darkplaces Player Names & Colors
+    Players can add color themes to their names. They're expressed either 
+    decimal or hexidecimal.
+
+    The decimal format follows
+        A character '^' that is not displayed, followed by a single digit 
+        between 0 and 9.
+    The hexidecimal format follows
+        A string '^x' that is not displayed, followed by 3 digits between 
+        0 - 0xF.
+
+Python Regex to C Translation
+
+    The snippets from the original python code:
+
+    _all_colors = re.compile(r'\^(\d|x[\dA-Fa-f]{3})')
+    _dec_colors = re.compile(r'\^(\d)')
+    _hex_colors = re.compile(r'\^x([\dA-Fa-f])([\dA-Fa-f])([\dA-Fa-f])')
+
+    _dec_spans = [
+     "<span style='color:rgb(128,128,128)'>",
+     "<span style='color:rgb(255,0,0)'>",
+     "<span style='color:rgb(51,255,0)'>",
+     "<span style='color:rgb(255,255,0)'>",
+     "<span style='color:rgb(51,102,255)'>",
+     "<span style='color:rgb(51,255,255)'>",
+     "<span style='color:rgb(255,51,102)'>",
+     "<span style='color:rgb(255,255,255)'>",
+     "<span style='color:rgb(153,153,153)'>",
+     "<span style='color:rgb(128,128,128)'>"
+    ]
+
+    ...
+
+    def html_colors(qstr='', limit=None):
+        ...
+        html = _dec_colors.sub(lambda match: _dec_spans[int(match.group(1))], 
+                               qstr)
+        html = _hex_colors.sub(hex_repl, html)
+        ...
+
+    html = _dec_colors.sub(lambda match: _dec_spans[int(match.group(1))], qstr)
+        The character following a '^' is treated as an index to the array 
+        '_dec_spans'. The corresponding element in '_dec_spans' replaces the 
+        character '^' and the following digit in the string 'qstr'.
+
+    html = _hex_colors.sub(hex_repl, html)
+        The output of function 'hex_repl' replaces matching strings in html- 
+        '^x' followed by 3 hexadecimal digits. The function 'hex_repl' has more
+        to do with the algorithms of color model conversions than it has to do 
+        with regex rules.
+
+    The control flow to output similar results to the regex substitutions is 
+    in the function
+        static void b(char * const str);
+    Unlike the python counterparts, it segments the player name into tokens and
+    prints strings also other strings instead of the sequences not intended to 
+    be displayed.
+
+Function Walkthrough
+Sorted by caller to callee.
+
+    void print_plname(const char *)
+        const char * parameter is the player's name. It is used as a basis for
+        the variable 'copy'. 'copy' will always be the shorter character string.
+
+        This is function is intended to be used by the client file.
+
+        This function unconditionally allocates memory (calloc) and frees it at
+        the end.
+
+        By itself, it only removes extraneous instances of the character '^'. 
+        It then calls the function
+            static void b(char * const)
+        where actual output occurs.
+
+    static void b(char * const)
+        const char * parameter is the player's name. The data pointed at by the
+        pointer is altered by function 'strtok', but the pointer itself is 
+        never changed. Abstractly, fragments of the player's name are treated 
+        as a command to print specific strings.
+
+        This function iterates once through the player's name. 'strtok' 
+        segments the player's name; sequences between and not including '^'s 
+        are treated as substrings. The first character of the substring is 
+        checked for a digit inclusively between 0 and 9 for a decimal color 
+        code. Exclusively or, checked for an 'x' and a numerical sequence 
+        afterwards for a hexidecimal color code. If the substring does not have
+        either, it is printed like an ordinary string.
+
+        This function may not be adequate when a player's name intentionally 
+        contains '^'.
+
+    static void hexspan(const char *) 
+        const char * parameter is ideally a sequence of 3 hexidecimal digits. 
+        Actually it is the entire substring from the callee. The first 3 
+        elements are of interest as 3 separate single digit numerical values 
+        and are explicitly separated to prevent function 'strtol' from 
+        interpreting them as multidigit numbers. These 3 elements are rgb 
+        values from the game engine.
+        Xonotic represents RGB values as a sequence of three digits 0 - 0xF. 
+        Before conversion is to be done, they must be multiplied by 0xF so the
+        full range of values for RGB, 0 - 255 can be represented.
+
+        This function prints the an html span tag.
+
+        This function will first convert rgb to hsl to check if the colors are 
+        too dark for the web page, and if so brighten up the colors then 
+        reconvert to rgb. 
+
+    static void decspan(const int)
+        const int parameter is a digit, the range being [0, 9].
+
+        This function is straightforward. It will print an html tag 
+        corresponding to the const int parameter.
+
+    void hsl2rgb(struct Rgb *, const struct Hls const *)
+        First parameter, 'struct Rgb *' is the result of the conversion. It 
+        does not need to be initialized.
+        Second parameter, 'const struct Hls const *' is the values and color
+        model to convert from and because, it must be initialized.
+
+        The math referenced from:
+            http://www.rapidtables.com/convert/color/hsl-to-rgb.htm
+        The implemenation deviates at the last 3 lines of code where the 
+        results are finalized and placed in the output. The webpage does not
+        mention that rounding up is necessary. However it is, otherwise the
+        nonzero rgb values for the following colors 
+            Silver  (0°,0%,75%)
+            Gray    (0°,0%,50%)
+            Maroon  (0°,100%,25%)
+            Olive   (60°,100%,25%)
+            Green   (120°,100%,25%)
+            Purple  (300°,100%,25%)
+            Teal    (180°,100%,25%)
+            Navy    (240°,100%,25%)
+        will be off by one.
+
+    void rgb2hsl(struct Hls *, const struct Rgb const *)
+        First parameter, 'struct Hls *' is the result of the conversion. It 
+        does not need to be initialized.
+        Second parameter, 'const struct Rgb const *' is the values and color 
+        model to convert from and because, it must be initialized.
+
+        The math referenced from:
+            http://www.rapidtables.com/convert/color/rgb-to-hsl.htm
+        The implementation deviates when calculating hue, when Cmax is R'. 
+        Instead of modulo, there is a summation by 6 when G' is less than B'.

+
+Overview
+
+    This component uses colors.c / colors.h.
+
+    Every function that allocates memory also frees it.
+
+    Advanced string manipulation such as concatenation is avoided. Instead
+    strings are printed in parts.
+
+Exo File Dependencies
+
+    SQL commands are stored in an outside file (.sql) and executed. The 
+    functions in this file are largely adaptable until 
+        void qresult(void * const, const char *);
+    which prints the results of the query. This is specific to the query. All 
+    functions in this file could be considered non-modular because the 
+    specialized functions like 'qresult' are eventually called by the more
+    adaptable functions. This may later be solved by calling function pointers
+    to display table data, but currently many of the tables are similar enough
+    that one function to print all tables suffices.
+
+Adding or Removing New Queries
+
+    To add new queries the program may handle the following functions need to 
+    be adjusted.
+
+        inline void print_tblheader(const char *);
+
+        inline char *get_filename(const char *) ;
+
+        void qresult(void * const, const char *);
+
+    The file name of the query file should be added to the switch statement of
+    function 'get_filename'. The starting html tags and labels should also be 
+    added to the switch statement of function 'print_tblheader'. For both 
+    forementioned functions, the switch statement operates on a variable 'c' 
+    which represents the first character of the query string. Currently, the 
+    case is that the different queries, '?map=' and '?player=', begin with 
+    different letters.
+
+    The function 'qresult'- extra formatting and corresponding conditions 
+    should be added to the series of if/else-if statements. 'qresult's most 
+    applicable conditionals are player names and formatted times- if a new 
+    query will involve those, the conditionals should be added.
+
+Function Walkthrough
+Sorted by caller to callee.
+
+    void getquery(char * const);
+        Parameter 'char * const' is the query string retrieved from the 
+        environment. NULL is an acceptable parameter. Only the first character 
+        of the string pointed at by the pointer will be changed.
+
+        A file name is then retrieved from 'get_filename', depending on the 
+        first character of the query string. Then the contents of the query 
+        file is read in to be later to query the database.
+
+        Currently, this function determines the size of the file by using 
+        'fseek' and 'ftell'. Often recommended against however:
+            1. The files to open are restricted to a specific set.
+            2. The files are plain text files.
+            3. The file sizes, in bytes, are very unlikely to exceed the 
+            maximum value representable by integers.
+
+        'ftell' returns a long int. It can determine the file size of a ~2 GB 
+        file.
+
+    int executequery(const char *, const char *);
+        Parameter #1 is the string containing the query for the database. NULL 
+        is not acceptable. If a null value is given, the program will output 
+        the following string to stderr:
+            Could not prepare SQL statement: not an error
+
+            (null)
+        Parameter #2 is the query string. NULL is acceptable.
+
+        This function opens and closes the connection to the database. Also 
+        prepares and finalizes the sql statement. However itself, it does not
+        actually query the database.
+
+    void qresult(void * const, const char *);
+        Parameter #1 is the prepared sql statement.
+        Parameter #2 is the first character of the query string- in use to 
+        identify the query.
+
+        This function both executes the query and displays the data.
+        The for loop iterates for each field of the row returned.
+
+        Conditionals explained:
+        
+        The fields are hardcoded from the sql query files.
+
+        mranks.sql       - (*c = QOVERVIEW)
+            select  mapid,   max(trank), min(tvalue), alias
+        i =         0       1            2            3
+
+        rplayers.sql     - (*c = QRPLAYER)
+            select  alias,   mapid,      idrank
+        i =         0        1           2
+
+        mleaderboard.sql - (*c = QMLEADERBOARD)
+            select  trank,   alias,      tvalue
+        i =         0        1           2
+
+        if ((*c == QMLEADERBOARD && i == 1) 
+            || (*c == QOVERVIEW && i == 3) 
+            || (*c == QRPLAYER && i == 0))
+            If the field is for map leaderboards and column 1, or the overview 
+            and column 3, or player ranks and column 0, then it is a player 
+            name; which should have the in-game color codes translated to html.
+
+        if ((i == 0 && *c == QOVERVIEW) || (i == 1 && *c == QRPLAYER)) 
+            If the field is for overview and column 0 or is player ranks column
+            1, then it is a map name, and it should have html tags linking it 
+            to the map leaderboards.
+
+        if (i == 2 && (*c == QMLEADERBOARD || *c == QOVERVIEW))
+            If the field is column 2 of either the overview or the map 
+            leaderboards, then it is a time which should be formatted as such.
+
+        If none of the conditionals are met, then the field is printed as usual.
+
+    void print_time(const unsigned char *);
+        Parameter 'const unsigned char *' is the string that represents a 
+        number- quantity of centiseconds.
+
+        The time as a string is converted to a number by 'strtoul'. Thus, the 
+        maximum value that is returned by 'strtoul' given a string is 
+        21,474,836.47 seconds. This is by far, more than enough for a game mode
+        focused on the lowest possible times.
+
+        This function performs the conversion and prints the value.
+
+    inline void print_tblheader(const char *);
+        Parameter 'const char *' is a pointer to a string. However, only the 
+        first character is of interest because C can not switch on strings.
+
+        This function prints the starting tag of the html table.
+
+    inline char *get_filename(const char *) ;
+        Parameter 'const char *' is a pointer to a string. However, only the 
+        first character is of interest because C can not switch on strings.
+
+        This function returns the file name of a sql query file.
